Triple Crown winner American Pharoah will join the Coolmore stallion roster in Australia in the spring.
In 2015, American Pharoah ended a 37 year-drought when he claimed the Triple Crown of the Kentucky Derby, Preakness Stakes and Belmont Stakes.
Later that year he added the Breeders' Cup Classic to his record.
He stood his first season in 2016 at Coolmore's Ashford Stud in Kentucky.
"We have been overwhelmed by interest from Australasian breeders in American Pharoah ever since he retired to stud in Kentucky," Coolmore Australia's Tom Magnier said.
"It's well recognised that he is a once-in-a-lifetime horse and the opportunity to bring him to Australia is an irresistible one.
American Pharoah will stand the 2017 southern hemisphere season at service fee of $66,000 (inc GST).
